Adafruit MCP4725 DAC
Description:
This module allows you to add an analog output to your microcontroller by based on the MCP4725, an easy-to-implement 12-bit DAC controllable in I2C.
Very useful in audio/analog, if the PWM is not enough, simply select an output value and this will be available on the vout.
It is possible to control 2 modules via the same I2C bus.
Technical data:
Dimensions: 18 x 14 x 3 mm.
Compatible with 3.4Mbps fast I2C mode.
EEPROM on the board to store the selected voltage value.
Compatible with 3.3V to 5V (the selected output voltage must not exceed the supply voltage).
